Two cars were set on fire just before 7 a.m. Saturday on Pratt Street. That fire spread to a third car.

While investigators were still processing the scene, they saw smoke billowing from another car down the street.

A third incident on Ashford Street was reported a short time later.

WBZ-TV’s Alana Gomez reports.

Fire officials say this marks eight such incidents in the area in less than two months.

“We heard an explosion and we thought someone crashed in front of the house and it kind of rocked the house,” said Constantine Zavris who lives at the home on Ashford Street with several roommates.

Heather Wilson also lives at the home, and said she believes the arsonist also tried to target her car before running away. Wilson found burnt pieces of paper and a charcoal briquette in her car. Wilson said she’s relieved the suspect left before successfully lighting her car on fire.

“He didn’t take anything he just set my passenger side on fire,” said Wilson.
